UNITED STATES PATENT OFFICE CHRISTIAN REICHMANN, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN LAMPS Specifieation f01ming art of Letters Patent N0. 21,5'46, daed September 21, 1858.

T0 all w7wm it may cozwern:

Be it known that I, CHRISTIAN REIOHMANN, 0f the eity and county 0f Philadelphia, and State of Pennsylvaniahave invented. certain new and useful Improvements in the Construeti011 of Lamps for burning oils that are heavily charged with earbon, such as benzole, kerosene, paraffine, 01 other coal-oils; and I do hereby declare the following to be a fullclear and exacb description of the construction and operation 0f the same, reference being ha(l t0 the aecompanying rawings, making a part; of this specifieation, in whieh Figure 1 represenns a perspecbive view 0f the upper part 0f bhe1arnp. Fx'g. 2 represents a vertical central section, and Fig. 3 represents the manner 0f attaching and supporting the open bell-shaped cap on the taube.

Similar letters of reference, where they 0ccur in the separate figures, denote like arts 0f the lamp in all 0f them.

I am aware that; lamps have been devised in which coal-oils are burned; bub they have serious objeetions, among which may be menbionecl as most prominent the number of manipulabions necessary -t0 light them, the darkening of the under part 0f the lamp, the lighl: being thrown entirely upward, the inability 0x trouble in filling them when burning, ancl, finally, the inaccessibility to the wheels f0r raising and lowering, and the taube for direcizing, the wick. By my manner 0f constructzing the larnp I avoid all tshese imperfections, and by a much more simple mode than heretofore praeticed I introduce the atmospheric air t0 the flamme above and below the slotted cap, without which supply of air the lamp will n0t burn without smoking.

The nature of my invention eonsists in the slotted open bellshaped cap%hat is, a cap which admits of the external air passing in between its outer margin and the chin1ney and which also allows the light; t0 be reflected downwarcl 01 toward the lamp as well es above it.

T0 enable others skillecl in the art 130 make and u-se my invention, I will proceed t0 describe the same with reference t0 the draw- 1ngs.

A represents a lamp, which may be of any 0f the ordinary forms. The eap or top a,thab covers the bowl of the la-mp, is of a cup shape, wil;h a broad flange, b, ab its top. There is a hole through the bobtom of this cap by whieh and the cup shape of seid cap the lamp may be readily repleuished while il; is burning. A slob i s made in the bobtom of the cap a, into which the lower end 0f a flat wick-tube, c, is inserted. and fastened. This tube c may be about two inches long, and has two vertical slots, c e, cut in in, through whieh the teeth of the two wheels d d pass and intao or againsb the wie]: f, passing through said taube. The wheels e e are permanently fixed 011 a shafb, g, supported in bearings h, attzaehed t0 the habe c, ancl a thumb-piece,j 011 the shaft; 01 rod g allows 1't to be easily turned, and thus raise 01' lower the wick. The cap a, tube c, r0d g,and its wheels are united and come otf togebher. They f01m the middle section 0f thelamp, the

stand and bowl forming the lower section thereof. There is also a third 01' upper section 0f the lamp, which completes in, and is as follows: z'is a slide 0r 100p that; fits over the flat; tube c, and when in place is supported thereon. On this slide i there are arms or brackets 0 0, t0 which the slotted open bellshaped cap m is attached and by which its is supporbed.

The open hell sl1aped cap is made as follows: A slob, n, eonsiderably larger than the wiek f, is made across the crown or dome of said cap, and ab its 0uter perimeter there is a. series of vertical arms 0r supporbs, k k k, &c. within and by wl1ich the chimney 12 is held.- The spaces between the arms k k are so cut away as thab the external air 1nay freely pass in to supply the la-mp underneatzh and behween the bottom of the chimneyp und the periphery 0f the said cap m. The chimney in my lamp may be straight, and not swelled oub around the fiame 'Il1e slot n being much larger than the wiek, the uecessary air bo efieeb proper combustion ab that poinb enters alongside 0f the wiek.

In will be perceived thab the mi(ldl@ secbion 0f the lamp exposes bat; little more surface than that 0f the -wick-tube alone. This procluces several imporbant; advantages besides the dispensing With several pieces entirely thal; have heretofore been used on this kind of lamp, viz: 111 allows the lamp to be filled while burning. In exposes the toothed wheels, tube, and wick tso view, so as to readily See wl1ether they are in order. II: allows the light frotn the uuder parl: of the bell-cap m to be reflected or thrown down toward tyhe lamp. 'Ib can be lighted by simply lifbing oft the chimney 01 by applying the Iight underneath the cap m, and the openness of the bell-cap m causes a better light bymaking 1ess shadow than heretofore.

Having thus fully described the natura and objecl: of my invention, what I claim therein .as new, and desire t0 secure by Letters Patent, iS-= In combination wibh the lamp, the slotted open bell-shaped cap m, when so consbructed, arranged, and operating as t0 allow the light; 170 be deflected downward, substantially in lhe manner and for t-l1e purpose herein sei; forth and explained.
